The madcap 26-year-old Bluebirds fan has spent four weeks and up to 40 hours transforming each City win – from Chasetown to Barnsley – into a mini Lego adventure.

The trainee actuary, who is a season ticket holder and club ambassador, said: “I was reading in a football magazine about a kid in Germany who had created dolls out of Lego for SV Hamburg and it got a bit attention. We had a discussion about whether it would be possible and that coincided with the win at Barnsley.

He created the pitch using a pool table and the ball is suspended from a piece of string on a pool cue which is balanced on two music stands.

Ashley, from Sully, in the Vale, spent hours designing kits, numbers and names, and sticking them on to his Lego team, adding distinctive characteristics, like Kevin McNaughton’s the way.

He used a digital camera to take thousands of snaps of the players at different points in the five matches – and using computer software to speed the pictures up to five per second, he made two videos.

The seven-minute videos even have commentary and action replays. “I think people think it’s slightly odd,” he said. “But once they’ve got past that everyone’s said it is really good.”

On internet video-sharing website YouTube, where the video was initially posted, it has been viewed more than 300 times.

Fans have logged on saying: “Pure genius” and “Nice one!” but others wrote: “Get a job”.

“One wrote ‘Have you got a girlfriend?’ and I was tempted to write back ‘Yes, I’ve made one out of Lego!’,” said Ashley.

But the big question is, will he create another one after the final?

“I was pretty sick and tired of it when I finished so it depends on the result,” he said. “If City win, then there’s a good chance!”
